Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that although the sub-frame of the current automobile can meet the strength, rigidity and modal requirements of the relevant installation points of the front sub-frame, its anti-collision ability is poor, so that it is difficult for the whole vehicle to meet the five-star collision requirements. Insufficient, provide a car front subframe with better anti-collision ability, so that the whole vehicle can meet the requirements of five-star collision

Abstract

The invention relates to the field of vehicle subframes, and an objective is to provide a vehicle front subframe. The vehicle front subframe comprises two symmetric edge beams, a front cross beam and a rear cross beam. The edge beam comprises a front segment, a front inclined segment, a middle segment, a rear inclined segment, a rear segment, a front lower energy absorption reinforcing plate, a rear energy absorption reinforcing plate, and a front upper energy absorption reinforcing plate. The edge beam is provided with a middle cavity. The front lower energy absorption reinforcing plate, the rear energy absorption reinforcing plate, and the front upper energy absorption reinforcing plate are arranged in the middle cavity. The vehicle front subframe is relatively good in collision-resistant capability, and a whole vehicle can achieve five-star collision requirement.

Description

technical field [0001] The invention relates to the field of automobile auxiliary frames, in particular to an automobile front auxiliary frame. Background technique [0002] With the rapid development of the automobile industry, people are paying more and more attention to the safety of people when vehicles collide. E-NCAP, Euro-NCAP (European New Car Assessment Program European New Car Safety Evaluation Association) is the most authoritative safety testing organization in the automotive industry initiated by the governments of five European countries. Jian, through the frontal impact test results at 64Km / h and the side impact test results at 50km / h, provide European consumers with a reference basis for car purchase choices; the crash test results are divided into one to five stars (five stars are the highest), and the test items For frontal impact, side impact, side cylinder impact, pedestrian protection and child protection in the car. The utility model of Chinese patent...
